Improvement in casting door-numbers



UNITED STATES IPATENT Ormea-C J. T. FULLER, OF LOISVILLE, KENTUCKY, ASSIGNOR TO HIMSELF AND JOS. LANDES, OF SAME PLACE.

IMPROVEMENT IN CASTING DOOR-NUMBERS.

Specication forming part of Letters Patent No. 27,86 l, dated April 10, 1860.

' accompanying drawings, forming a part of this specification, in which- Figure l represents a design cast for a doornumber, showing the numbers cast solid with the frame. Fig. 2 is a View ot' the pattern from which the desi gn of Fi g. l may be molded and cast. The numerals are, however, removed from the pattern in order to show the bars for securing the numerals within the frame from vwhich the mold is to be taken. Fig. 3 is a transverse section of Fig. 2, showing the manner of securing the numerals to the same. Fig. 4 is a perspective view of one of the numbers of Fig. l, showing the projections on the back of the same for securing it to two bars. Fig. 5 is a side or end view of one numb er, having a dovetail slot formed on its back for receiving one bar for grasping the same.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in a novel arrangement and construction of patterns for casting such signs as door-numbers, signs, or numbers for hotel-doors, church-pews, or numerals or letters and designs of any description where they are grouped together and surrounded by a frame-work ot' any design, by which const-ruction I am enabled to change the letters, numerals, or other metallic designs and substitute in the pattern others of a different style or character, thus employing only one frame-pattern for any letter or combination of letters. The .mold is formed from thc pattern thus prepared and the casting taken in the usual -IDZLIIDGR To enable those skilled in the art to fully understand my invention, I will proceed to deent numbers and diii'erent combinations of numbers which have to be changed an indelinite number of times.

In the drawings, A Al represent a pattern, made in two parts, which parts are secured together by screws or in any other convenient way. B l5 are two parallel bars, having their inner edges beveled inward and their top or face surfaces slightly above the surface ofthe frame A. These bars are secured to the frame A at their ends, and are for the purpose of receiving numerals, letters, or other suitable designs which it is desirable to cast with the frame.

N ow, it will be understood that I do not conline my invention to the two bars B B and this particular size and design of frame shown in the drawings, but the point of invention consists in a novel manner of placing letters, numerals, or other characters in a suitable frame, wherein they will be retained in place in this frame, so that a mold may be taken in sand or other suitable 1n aterial, and from which frame they may be readily removed and other characters introduced in their stead. For this purpose the letters, numerals, or other designs are furnished on their back surfaces with ribs or projections a a, with their outer edges beveled inward, as shown by Figs. 3 and 4. These letters are then secured to the bars B B in the A frame by simply sliding them on the bars, and the beveled surface of the bars with the beveled surfaces of the ribs on the letters form a dovetail attachment, which will allow the letters to be slid on or oii' the bars as often as they are to be changed.

Instead of using two bars and securing the letters at their top and bottom, as above described, the two ribs a a may be brought closer together,so as toform dovetail slots on the backs of the movable designs. With such slots one bar will serve to secure the designs, and this bar should be beveled so as to correspond with the slot in said designs. With this arrangement the letters, numerals, or other designs may be readily grouped together in any desired combination, and they may be removed and others placed on their bars and secured while an impression in sand or other material is taken of the combination so formed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

Forming suitable ribs or projections, a a, on or bars and others introducedy at pleasure, subthe backs of`1etters, numerals, symbols, or stantially as and for the purposes herein deornamental designs of any description in such scribed and represented. a manner that they may be clamped and held by a bar or by bars, B B, in suitable combina- Witnesses: tions While au impression insand or other ma SAML MATLAGK, terial is taken, and then removed from the bar D.
